SASH-LOCK.

Patented Dec. 21, 1909.

Application filed June 4, 1909. Serial No. 500,070.

To all whom 'it may concern:

Be it known that I, FRED G. SOHAURER, a citizen of the United States ofAmerica, residing at lVellington, in the county of Sumner and State ofKansas, have invented new and useful Improvements in Sash- Locks, ofwhich the following is a specification.

This invention relates to sash locks, and one of the principal objectsof the same is to provide simple and efficient means for looking a sashin any desired adjustable position by a simple and easily operateddevice.

Another object of the invention is to provide a sash lock which willpermit the easy adjustment of the upper or lower sash and will hold thesame in locked position when adjusted, said lock comprising a perforatedmetal strip secured to the sash and a spring dog secured to the windowframe, said dog having a stud adapted to engage any one of theperforations in the strip, means being provided for unlocking the springdog.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawing, in which,

Figure 1 is a View looking at the inside of a portion of a window framehaving sashes mounted therein, each sash being provided with a sash lockmade in accordance with my invention. Fig. 2 is an enlarged elevation ofthe spring dog, the base portion thereof and the window casing beingshown in section. Fig. 3 is a sectional view taken on the line 3-3 ofFig. 2, looking in the direction indicated by the arrow.

Referring to the drawing, the numeral 1 designates the window casing; 2is the lower sash, and 3 the upper sash. Secured to one of the sides ofthe lower sash is a metal strip or bar 4 provided with a series ofperforabar being secured flat upon the sash by means of screws (3 at theopposite ends thereof.

The locking device comprises a spring dog consisting of a spring metalplate 7 having a curved portion 8 therein and an inwardly projectingstud 9 secured to the lower end thereof. The spring 7 is secured in theslot of a stud 1O projecting outward from a base member 11, said basemember being secured to the window casing by means of screws 12. Thespring is held in the stud 10 by means of pins or screws 13. A key ismounted in a socket 1 1 in the base member 11, said key comprising ashank 15 held in the socket by means of a pin 16. Formed on the key is aprojecting bit 17 and a handle 18 extends to one side from the outer endof said key.

As shown in Fig. 1, the lock and key are located at the upper portion ofthe lower sash 2. The upper sash is provided with a locking device ofidentical construction, but the lock and key are located at the lowerend of the perforated strip; hence a description of the lock for thelower sash will serve as a deslcription for the lock secured to theupper sas 1.

The operation of my invention may be briefly described as follows :-Inthe position shown in Fig. 1 the lower sash 2 and the upper sash 3 arelocked in closed position. Should it be desired to raise the lower sashthe handle 18 of the key is turned outwardly, the bit 17 engaging thespring 7 to withdraw the stud 9 from the aperture 5 in the strip 4. Thesash is then raised to the desired height, and the handle 18 is turnedback to the position shown in Fig. 1 to permit the stud 9 to enter oneof the perforations 5 to lock the sash in adjusted position. The uppersash 3 may and locked.

My invention is simple in construction, of few parts which cannotreadily get out of order, can be quickly operated and will hold the sashat any required adjusted position, or will lock the sash closed.

I claim 1. A sash lock comprising a perforated metal strip secured tothe sash, a spring dog connected to a base member secured to a windowcasing, said spring dog comprising a spring plate secured at one end toa stud projecting from the base member, said spring being curved andprovided with a stud to engage any of the perforations in the strip, anda key mounted in the base member and provided with an extended bit toengage said spring for releasing the stud from the perforations.

2. A sash lock comprising a metal strip having a series of perforationstherein, said strip being secured to the sash, a base member providedwith an outwardly projecting slotted stud and an inwardly projectingsocket, a spring dog secured in the slot in said stud and provided witha curved porbe similarly adjustedtion'and an inwardly projecting stud toen-- gage said perforations, a key provided With a shank pivotallymounted in said socket, said key being provided with a bit adapted toengage said spring for releasing the stud from the perforations, and ahandle for operating said key.

In testimony whereof I affix my signature in presence of two Witnesses.
